1. ## Perpendicular Height

Can some one help me with perpendicular height -if u have all the side measurements of a triangle how do u find the perpendicular height?

2. Using Pythagoras, probably.

Lay the triangle on its side and draw the perpendicular height you're supposed to find. Then you got 2 right angle triangles.

Let h be the perp height and c = a+b be the length of the base (where a and b are the lengths to the perpendicular h.

Then you have two equations $h^2 = a^2 + p^2, h^2 = b^2 + q^2$ where $p, q$ are the lengths of the sloping sides.

Can you draw it? I can't be bothered myself, it's too much like hard work for me.
